    XLR got the latest incarnation of the N* (until the supercharged edition arrived.) I don't recall reading any posts regarding head gasket issues on any XLR forum in the past six years.

    Head gasket problems went away in about 2000 when GM installed longer head bolts. Original (earlier) bolt pulled up and out of block, stripping the threads.

    I haven't heard of a longitudinal N* blowing head gaskets yet.
    There are some pretty big differences between the XLR engine and that in a transverse configuration.
